The US and Iranian negotiation teams may return to Islamabad later this week, five sources told Reuters on Tuesday, days after the highest-level talks between the two countries in over a decade ended without results.

“No firm date has been set, with the delegations keeping ⁠Friday through Sunday open,” a senior Iranian source said.

Two Pakistani sources said that Islamabad is talking to both sides about the timing of the next round, and it will likely take place on the weekend.
